The intercept spacer is metallic. Think of it this way. It get's cold outside, the outside pane of glass gets cold. The metal spacer touching that outside pane of glass gets cold, and conducts that cold to the inside pane of glass. Glass has about no insulative qualities whatsoever, so now at some level, cold is being conducted into your house. That's the theory.
Superspacer is foam and has no conductivity. TPS is an organic rubber. Unlike a metallic spacer, as the glass contracts and expands, the soft spacers move with the glass, cutting down on the possibility of seal failure over a metallic spacer.
Alot of manufacturers are using super spacer. TPS, for now, is only available on Schuco windows, but I believe others are trying to license it's use for their products.

HipKat is correct. PPG the manufacturer of the Intercept spacer calls it "warm edge technology" in comparison to the old aluminum spacers. The u shaped steel is less conductive than aluminum, but it is a conductor nonetheless. Windows with metal spacer systems will have a colder temperature at the edge of the glass, and therefore be more susceptible to condensation. The metal spacers also have a much higher likelihood of seal failure as well, which really is the most likely problem to arise with thermal panes anyway. TPS (Schuco) is the best seal system out there, period. Superspacer would be second.

You give a lot of stock in that hundreth of an inch of sealant Researcher. Here is a diagram of intercept similar to what you saw, and then what it really looks like. As you can see, the spacer is much closer to the glass than in the diagram.

Intercept is a great improvement over what prededed it and is acceptable in a window,... though Superspacer and TPS will do better job of keeping the inside glass warmer. TPS will also do a much better job of gas retention.

Great pictures for showing the desiccant filled belly too. There's enough in there to absorb infiltrating moisture and hide seal failures for atleast 10-15 years. It's kind of like buying a new boat with a hull full of sponges.

Absolutely Hipcat... that's the purpose of desiccants... to hide seal failures and control moisture present in partially filled I.G. units. Research some window spacer desiccant suppliers... they brag about how their products will conceal infiltrated moisture longer than the competition and keep windows from fogging longer. SIGMA (Sealed Insulated Glass Manufacturers Association) was asked to do a study for the USDOE in 2000. They actually cut open window units that were up to 20 years old. The tested for moisture in the desiccants. The BEST units had 4%-10% failure rates. It's about time a few manufacturers invested in technology to avoid the failures instead of hiding them.

I have heard, from more than one source, that the Argon will escape right through the glass itself over time. I am not sure, but i feel this is true. It may take a long time, but nether the less, it will happen. What do you guys have to say about this?
